Une fois que tu connais ta clé il est possible à partir de Fedora d'utiliser dislocker pour décrypter ta partition ou fuse-dislocker pour accéder à celle-ci:
Dislocker has been designed to read BitLocker encrypted partitions ("drives") under a Linux system. The driver has the capability to read/write partitions encrypted using Microsoft Windows Vista, 7, 8, 8.1 and 10 (AES-CBC, AES-XTS, 128 or 256 bits, with or without the Elephant diffuser, encrypted partitions); BitLocker-To-Go encrypted partitions (USB/FAT32 partitions).
The file name where the BitLocker encrypted partition will be decrypted needs to be given. This may take a long time, depending on the size of the encrypted partition. But afterward, once the partition is decrypted, the access to the NTFS partition will be faster than with FUSE. Another thing to think about is the size of the disk (same size as the volume that is tried to be decrypted). Nevertheless, once the partition is decrypted, the file can be mounted as any NTFS partition and won't have any link to the original BitLocker partition.

A mount point needs to be given to dislocker-fuse. Once keys are decrypted, a file named 'dislocker-file' appears into this provided mount point. This file is a virtual NTFS partition, it can be mounted as any NTFS partition and then reading from it or writing to it is possible.
